We started making rc power supplies a few years ago when how rc car batteries were being charged in the Arizona rc car stock racing scene started pushing the envelope. At first it was thought that you had to have an iCharger to be fast and then slowly the amount of amps you had to charge at increased as the battery technology improved. Once racers pasted the 20-30 amp charge rate and approached the 40 amp mark racers were stacking 2 large, lower powered power supplies to achieve the needed wattage the iChargers were requiring to pump 40 amps into a 2s lipo battery. Like a few others, we came across small server power supplies with ample power output that could be converted (with a little work) to provide more than the needed power we required without the expense and hassle of having to purchase 2 larger power supplies and lug them around just to try to be a fast guy racing an rc car in a stock class. Once other racers saw what we were doing we had quite a few requests to make one for them. As word spread about these we found that we could purchase them in bulk to get the cost down quite a bit which we then pass on to our fellow racers.
We currently have 4 different units available for sale that vary in power output and options slightly. First up we have a 12 volt, 75 amp unit that puts out 900 watts of power. Second is our 75 amp unit with a 5 volt, 3 amp usb port added. Third is the big brother to the 75 amp unit that puts out 12 volts, 85 amps at 1025 watts of power. Our forth unit is our flagship model which is a 12 volt, 85 amp at 1025 of power output with a 5 volt, 3 amp usb port added. These specs are with 110 AC input. Each of these can be used with 220AC and will yield a slightly higher output at 220 AC.
Each unit comes with 3 pairs of 4 mm bullets to be able to offer power to 3 devices at once. They are small measuring 1.5 x 3.5 x 9 inches in size and weigh around 3 lbs.
Once they are tested, each unit is wrapped in black carbon fiber vinyl for a classy look and capped off with a 3D printed cover to protect the 4 mm bullets. One key feature is the fan is automatically regulated and ramps up and down based on heat which means they run quiet unless under a heavy load.
